The Prime Minister has said those seeking to justify IRA terrorism "should be ashamed of themselves".

David Cameron was responding to a question from North Belfast MP Nigel Dodds.

The DUP deputy leader raised the comments of the new shadow chancellor John McDonnell who said the IRA should be honoured for their role in the peace process and called on the Conservative leader to denounce those sentiments.

Speaking in the House of Commons today, Mr Dodds said the deaths of MPs Airey Neave, Robert Bradford, Ian Gow and Sir Anthony Berry were a reminder of the "savagery of the brutality of terrorism".

"As are the gravestones across Northern Ireland and this land," he said.
